1. ORIENTATION
1.1 Overview
This manual addresses B&B ARMR Model 400 Series sliding cantilever gate vehicle
barriers. The 400 Series barriers have high stopping power, and are designed to stop and
disable a vehicle that tries to breach them. They are one in a series of anti-terrorism vehicle
barrier designs manufactured by B&B ARMR.
There are currently several models in the 400 Series: Model 400, Model 400A, Model 450,
and Model 450A . The general descriptions of these basic models are as follows:
Model 400—a sliding cantilevered crash gate rated to stop a 15,000-pound
vehicle traveling at 30 miles per hour.
Model 400A—a sliding cantilevered crash beam rated to stop a 15,000-pound
vehicle traveling at 30 miles per hour.
Model 450—a sliding cantilevered crash gate similar to the Model 400 but with
a higher stopping power, the barrier is rated to stop a 15,000-pound vehicle
traveling at 50 miles per hour.
Model 450A—a sliding cantilevered crash beam rated to stop a 15,000-pound
vehicle traveling at 50 miles per hour.
Figure 1-1 will orient you to the three basic components of a 400 series vehicle barrier.
